Answer:
one: 9
Two: D
Step-by-step explanation:
One
The symbol used is x≥8 so 8 is included in the function part. That would mean that F(x) = 9
Two
The value you need to use is -4x + 3. That's because -2≤x and the symbol ≤ makes - 2 inclusive.
-4(-2) + 3 = 8 + 3 = 11
3a
The function is decreasing over -4x + 3
It goes from 11 to -29 roughly. That means it's going from a positive to negative number. Definitely decreasing
3b
The function is a constant when x≥8. The value of the function is 9 no matter what x is.
3c
The function is increasing from - 2x to 8 which is going from -9 to 11
Hey there!
4 + 5x + 66 = x + 10
70 + 5x = x + 10
5x + 70 = x + 10
SUBTRACT x to BOTH SIDES
5x + 70 - x = x + 10 - x
5x + 70 - 1x = 1x + 10 - 1x
SIMPLIFY IT!
4x + 70 = 10
SUBTRACT 70 to BOTH SIDES
4x + 70 - 70 = 10 - 70
SIMPLIFY IT!
4x = -60
DIVIDE 4 to BOTH SIDES
4x/4 = -60/4
SIMPLIFY IT!
x = -60/4
x = -15
Therefore, your answer is: x = -15
Good luck on your assignment & enjoy your day!

Y=5^x when x is 2.
y=5^2
y=25
Hope this helps!
Answer:
Sam's student council spent $39 on backpacks + paper and pens.
Step-by-step explanation:
They bought 3 backpacks for $7 each. 3 x 7 = $21.
They also filled those backpacks with paper and pens costing $6 each. 3 backpacks x $6 = $18.
Now, add the two prices.
18 + 21 = 39

Answer:
y=72
Step-by-step explanation:
Hey There!
So the Triangle angle sum theorem states that all of the angles in a triangle add up to equal 180
So all we have to do is subtract the given angles from 180 to find the missing angle
180-59-49=72
Thus y=72
